Help¶

This option indicates that we are building a Zephyr image that is intended to execute in normal mode. Execution of this image is triggered by secure firmware that executes in secure mode. The option is only applicable to ARC processors that implement the SecureShield.

This option enables Zephyr to include code that executes in normal mode only, as well as to exclude code that is designed to execute only in secure mode.

Code executing in normal mode has no access to secure resources of the ARC processors, and, therefore, it shall avoid accessing them.
